RZ Sge in probably superoutburst

 RZ Sge, one of UGSU stars, is undergoing a bright outburst. This outburst is
probably a superoutburst though the elongation is poor.
 Last superoutburst occurred in Aug. of 2005. Since this star has undergone 
superoutbursts at about one year intervals, we missed an outburst around Jan.
 of 2007 due to the conjuction.
